ABSTRACT
Recent Internet applications, such as the World Wide Web, tie
together a great diversity in data formats, client and server
platforms, and communities. This has created a need for media
feature descriptions and negotiation mechanisms in order to identify
and reconcile the form of information to the capabilities and
preferences of the parties involved.
Extensible media feature identification and negotiation mechanisms
require a common vocabulary in order to positively identify media
features. A registration process and authority for media features is
defined with the intent of sharing this vocabulary between
communicating parties. In addition, a URI tree is defined to enable
sharing of media feature definitions without registration.
This document defines a registration procedure which uses the
Internet Assigned Numbers Authority (IANA) as a central registry for
the media feature vocabulary.

1 Introduction
Recent Internet applications, such as the World Wide Web, tie
together a great diversity in data formats, client and server
platforms, and communities. This has created a need for media
feature descriptions and negotiation mechanisms in order to identify
and reconcile the form of information to the capabilities and
preferences of the parties involved.
Extensible media feature identification and negotiation mechanisms
require a common vocabulary in order to positively identify media
features. A registration process and authority for media features is
defined with the intent of sharing this vocabulary between
communicating parties. In addition, a URI tree is defined to enable
sharing of media feature definitions without registration.
This document defines a registration procedure which uses the
Internet Assigned Numbers Authority (IANA) as a central registry for
the media feature vocabulary.
This document uses the terms MUST, MUST NOT, SHOULD, SHOULD NOT and
MAY according to usage described in [8].
